Question

5. a. There are 250 mg in a dosage of a particular medication. How many grams is
this? Use the fact that there are 1,000 mg in 1 g.
b. Convert the rate 250 mg/hour to g/day.

Answer 1

a.

We know that there are 1000 mg in one gram then we have:

$250\text{ }mg\frac{1\text{ }g}{1000\text{ }mg}=0.25\text{ g}$

Therefore, 250 mg is equal to 0.25 g.

b.

To change the rate we need to remember that there are 24 hours in a day, then:

$250\text{ }\frac{mg}{h}\cdot\frac{1\text{ g}}{1000\text{ mg}}\cdot\frac{24\text{ h}}{1\text{ day}}=6\text{ }\frac{g}{day}$

Therefore, the rate is 6 g/day
